It's not completely ridiculous. Everyone is ALREADY "why not me" in IM2, and would only be moreso if he produces 47 suits in IM3. The idea that Tony isn't giving out armor like candy is true, however, he clearly doesn't fight vehemently against War Machine or else that IM2 rooftop ending scene would have been quite different. If there was anyone else IM would be okay having armor (especially if it were under his remote control) it would be Pepper.
